Update shared library major version to 10

The upcoming 3.1 release contains non-compatible API changes, though
they only affect parts of the interface that are extremely unlikely to
have been used outside of qpdf itself.  The methods and data types
affected were used for communication between QPDFWriter and QPDF and
would have had no real use in end user code.
